Abstract: FIELD: blasting operations. 
     SUBSTANCE: invention relates to explosive destruction of rocks using multi-row short-delayed blasting and can be used in various industries, which use blasting operations in rock massifs of rocks. Method of blasting operations taking into account pre-destruction zone includes construction of model of development of mass explosion in time and space for a specific blasting scheme with specific deceleration intervals higher than 25 ms/m, differentiated calculation of value of well charges for various areas of damping of massif by zones of prefracturing, evaluation of explosion results as per data of excavation of rock mass and selection of optimum parameters of explosion according to statistics. Starting pulse for explosion is provided simultaneously for two cut-off rows arranged along the block edge. Second or third row of borehole charges is taken from the edge of the block. Said deceleration interval is taken one stage lower than in perpendicular direction along rows of boreholes. 
     EFFECT: invention makes it possible to increase intensity of rock massif weakening in the middle part of the exploded block due to mutual overlapping of pre-destruction zones from two cut-off rows along its edges.
